This may be a bit off topic but I just got a fair amount of money I can spend toward improving my library. Unfortunately I don't have a lot of space so I want to put as much as possible into electronic resources. Since I already have the Logos/libronix system I will probably stick with that. But I need some advice. Which works do you consider the most important ones for me to consider?
Sincerely,
Michael Abernathy

I would repeat everything Louis listed, plus, if you still have money left over (I would prioritize these over the commentaries, but after the Original Languages Bundle and lexica):
Josephus
Philo
Greek OT Pseudepigrapha
Dead Sea Scrolls
Robertson's Grammar
